T @ZZ whom/ t may concern:

Be it known that we, EUGENE ALPHONSE GUEDENEY and EDOUARD EUGENE HARLES,

I citizens of the French Republic, residing at Paris, France, haveinvented Improvements in and Relating to Arresting Devices for Doors,Gates, or the Like, of which the following is a specification.

Ihe present invention relates .to arresting devices for doors, gates,and the like, and has for its object to construct an improved buffer,abutment, or arresting stop or catch therefor. This arresting device isfitted byV one of its parts into the floor or ground, and a movableinterior part under the action of a spring is normally in a projectingposition and can be sunk or lodged momentarily in its frame or settingby simple pressure in order to free the door or gate from the obstacleif it is desired to utilize the apparatus as an arresting device-forexample, in the case where the door or gate is provided with aclosing-spring. Further, in order that the apparatus may not causeinconvenience when sweeping or rubbing the ground or floor or in anyother circumstances the movable part can remain completely sunk by meansof an interior stop which is fixed to it and which is lodged in theangle-joint of a groove-guide provided for this purpose, thus hinderingYthe action of the spring at this moment. In certain cases there mightalso be disposed several stops and grooves.

In the accompanying drawings, which show by way of example several formsof carrying out this invention, Figure 1 is an exterior view; Fig. 2, avertical section, and Figs. 3, 4, 5 are modified constructions.

The apparatus comprises a tubular part a, of metallic or any othersuitable material, having at its bottom a seat or plate b and carryingone or more grooves c with angle-joints. Into the tubular part a entersa second tube d with a seat e at the top, which carries one or morestops f, taking, respectively, into one or more corresponding grooves c.The top of the tube OZ is provided with` either a thin plate of sheetiron or gauze g or with small metallic projections or any other suitablearrangement having for its object to permit the easy turning of theinterior tube with the foot. At the interior of this tube is lodged aspiral spring h, which is connected to the bottom of the tube a, and thetop of the tube d. This spring has for its object to raise the tube dwithin the limits permitted by the stop f and the groove c and at thesame time to cause'it to turn to the right or to the left.

Fig. 3 shows a form of construction in which the tube d carries at itsupper part a rubber head fixed, for example, by a screw j.

In Fig. l it will be noticed that the tube OZ carries at its upper parta prolongation k of restricted diameter, on which can be adapted arubber ring r1.

The arrangement shown in Fig. 5 comprises a similar apparatus to thatshown in Fig. 1, with the addition of a socket or case m, forming anoil-bath and closed at the bottom, into which enters without play thepart a. The bell-mouth n then receives a certain quantity of oil whichwill insure lubrication of the different parts of the apparatus. Thistype should be convenient in installations of paved or stone parts orothers of asimilar kind which are frequently washed, the bed of oillodged in n preventing the water penetrating into the interior of theapparatus and rusting purpose in the floor or ground in such a man nerthat its upper part is flush therewith, only allowing the interiormovable part to extend therefrom. When it is desired to cause the tubeforming the arresting device or abutment to disappear, it is sufficientto rest the foot on its upper part, which will cause the stop f to turnin the angle-joint of the groove c, an operation which will befacilitated by the action of the spring. Again, when it is desired toraise the arresting-tube a slight pressure is caused on its upper partby turning in a direction contrary to the tension of the spring,

which will then be actuated and return the parts to their originalposition.

Although we have described above several modifications of our invention,we do not desire to restrict ourselves to those specifically shown, asit is obvious that details might be considerably modified withoutdeparting from the spirit of our invention.

Having now particularly described and ascertained the nature of our saidinvention and in what manner the same is to be performed, we declarethat what we claim is- 1. Adevice of the character described,connprising an exterior tube adapted to be fixed in the ground or floor,a tube therein mounted for longitudinal and partial rotary movement, anda spring within said tube and having its ends so connected to the bottomof one of said parts and to the top of the other as to cause them toturn.

2. A device of the character described, cornprising an exterior tubeadapted to be fixed in the ground or iioor, a tube therein mounted forlongitudinal and partial rotaryT movement, and a spring within said tubeand having its ends connected to the bottom or' the one tube and to thetop of the other and constructed to move the same outward, and at thesame time to cause it to turn to the right 0r the left, and an exteriorcase closed at its lower end and having a bell-mouth and adapted toreceive oil, as and for the purpose specified.

3. A device of the character described, cornprising an exterior tubeadapted to be fixed in the ground or floor, a tube therein mounted forlongitudinal and partial rotary movement, and a Aspring within said tubeand having its ends connected to the bottom of the one tube and to thetop of the other and constructed to move the same outward, and at thesame time to cause it to turn to the right or the left, the saidexterior tube being formed with bayonetgrooves and the inner tubeprovided with lateral stops engaged therein, said inner tube beingautomatically rotatable by pressure upon its outer end, said outer endbeing provided with a roughened surface.

In witness whereof we have hereunto set our hands in presence of twowitnesses.
